Why it works: Butter and milk are a kitchen classic. They rank in the top 7% of all ingredient pairs, and cooks put them together in 81,283 recipes. Both carry (z)-4-heptenal, which smells biscuit, cream. The science ↓
Plum Cake, Common
Ingredients
Directions
The book says “a good oven”. The 350°F (175°C) in the steps is the modern equivalent, not the book's own figure.
Prepare
Preheat your oven to 350°F (175°C).
Rub the butter into the flour.
Add the sugar, currants, and allspice.
Make the dough
Warm the milk, stir in the yeast, and mix everything into a dough.
Knead the dough well and place it into 6 buttered tins.
Let the dough rise near a warm place for nearly an hour.
Bake
Bake the cakes for 1 to 1½ hours.
To check if done, insert a clean knife into the middle; it should come out clean.

Flour and butter barely smell alike, yet cooks put them together in 124,287 recipes: they work on texture and structure more than aroma.
Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Flour
- Provides the structure that holds the cake together as it bakes.
- Butter
- Rubbed into the flour, it adds richness and a tender crumb.
- Fresh yeast
- Produces gas as it ferments, which makes the dough rise and become light.
- Moist sugar
- Adds sweetness and helps keep the cake moist and browned.
- New milk
- Hydrates the flour and yeast so they form a workable dough.
- Allspice
- Contributes a warm, spiced aroma to the cake.
The step that matters
Let the dough rise near a warm place. Yeast needs warmth and time to ferment and produce gas. Rising fully gives the cake its lift and light texture, while an under-risen dough bakes up dense.
Swap the currant
